Following mass lead poisoning of workers at the Chinese-owned “Srbija Ziđin Koper” mine in Bor, Serbia last November, the mine’s union is raising concerns about regulatory enforcement. The incident prompted investigations into working conditions and safety protocols at the facility. Union representatives allege insufficient state oversight and a failure to ensure legal compliance by the company. The mine, a major employer in the region, has faced previous accusations regarding environmental and worker safety. Authorities have stated their commitment to holding all companies accountable to Serbian law, but the union seeks more concrete action. The long-term health consequences for affected workers remain a significant concern, alongside broader questions about the impact of mining operations in eastern Serbia.
